Above-mentioned main packing bag 14 is made by folding membraneous material 13, and described folding membraneous material 13 is set between the lower part of each membraneous material sheet 11,12.So that the folding edge 13a of membraneous material 13 directly makes progress, heat-seal film material piece 11,12 opposed edges parts form side heat sealing part 16, and the bottom of heat-seal film material piece 11,12 form thermosealed bottom and divide 17.
Form above-mentioned membraneous material sheet 11,12,13 by same plastic material.For this membraneous material sheet, can adopt laminate film to make, for example, mylar by 12 μ m thickness, the aluminium foil of the thickness of 9 μ m, the polyethylene foil of the thickness of 50 μ m constitutes, and perhaps is made of the mylar of 12 μ m thickness and the polyethylene foil of 50 μ m thickness.
Above-mentioned linear fastener 15 is made up of box element 18 and pin thread element 19, as shown in Figure 2.Open end along main packing bag 14 is provided with linear fastener 15, and linear fastener 15 is by corresponding length, this corresponding length is by from the overall width of main packing bag 14, deducts the heat sealing part 16 at edge and obtains, as with represented among Fig. 1.
Be contained in content in the packaging bag 10 of self-standing type Reclosable the shape of square or rectangle can be arranged.In this case, the packaging bag 10 of the Reclosable of self-standing type can be out of shape the parallelepiped shape that becomes cube or rectangle.Best, the part of easy bending is set, for example, indentation is set, so that make the packaging bag distortion easily at the box element 18 of linear fastener 15 and the sweep of pin thread element 19.And, preferably reduce two box elements 18 and pin thread element 19 end portion thickness, so that form thin part.
Fig. 2 represents the example of box element 18 and pin thread element 19, in the forming process of main packing bag 14, linear fastener 15 is connected on the main packing bag 14.Box element 18 and pin thread element 19 are connected respectively to the top 11a of the membraneous material sheet 11,12 of main packing bag 14, on the 12a.Top 11a, the 12a opposed side edge does not connect mutually.
